This is a NeoPixel stick from Adafruit. It contains 8 RGBW (red, green, blue, white) LED lights. Each LED is individually controllable. This allows you to create excellent lighting effects and LED projects. This version comes with a warm white RGBW version. The stick is also available with natural white and cool white.
The NeoPixel is split, half is RGB and half is a white LED. There are 8 of the small 5050 (5x5mm) smart RGBW LEDs per board. There are 2 mounting holes available to attach the board to your project. 8 LEDs not enough? That's no problem you can connect these sticks together. Youcan connect as many as you want, while only using one microcontroller pin. Each LED is individually addressable because the driver chip is inside the LED. They each have ~18mA constant current control so the color remains very consistent. This even when the voltage varies. There is no need for external choke resistors which makes the design slim. Supply the whole thing with 5VDC (4-7V will also work) and you are ready to go.
NeoPixel LEDs use a 800kHz protocol, so specific timing is required. On NeoPixels the PWM speed is ~400Hz, this works well but is noticeable when the LED moves.
You can connect the LED sticks by connecting the output of one stick to the input of another stick. There is a single data line with a very timing specific protocol.Because the protocol is very sensitive to timing, a real time microcontroller is required such as an AVR, Arduino, PIC, mbed, etc.Itcannot be used with a Linux based microcomputer or interpreted microcontroller such as the NetDuino. Adafruit has a NeoPixel library for Arduino which makes it easy to use. An 8MHz or faster processor is required. Wiring tutorials are available on the Adafruit site .
